Title: Coincidence detecting circuit
Inventor: YODA KAZUHIKO
IPC: H03K19/21
Filed: 1987-02-19
Abstract: PURPOSE:To operate the titled circuit with a low current consumption so as to prevent switching transistors (TRs) switched periodically from being turned on simultaneously. CONSTITUTION:A precharge signal inputted to an input terminal P at first goes to a logical '1', and a logical '0' inverted by an inverter N3 is fed to a gate of a P-channel MOS TR Q6', which is turned on and electric charge is supplied to a power supply line L1. Simultaneously, the inverted logic value '0' is inputted also to a gate of an N-channel MOS TR Q5, which is turned off, the power supply line L1 is disconnected from ground independently of the logical values of data A, B to keep the logical value '1' with the supplied charge. Then the precharge signal goes to logical '0' and the logical value '1' inverted via an inverter N3 is fed to each gate of the N-channel MOS TR Q5 and the P-channel MOS TR Q6', and the TR Q5 is turned on and the TR Q6' is turned off. Thus, the circuit is operated at a low current consumption.

Filed: 1996-02-27
Abstract: PROBLEM TO BE SOLVED: To improve the efficiency of formation and prevent damages to a tube during its use by a method wherein a side surface of a core member is formed with many whisker-like projections. SOLUTION: A core member 1 is made such that its upper end is integrally formed with a master frame 2. Then, a semi-circular vane 3 and whisker-like projections 4 are integrally casted and formed at the side surface of the core member 1. A cooperating seat 5 is made of anti-acid resin such as PE or the like and this is forcedly inserted into and fixed to the lower end of the core member 1. With such an arrangement as above, a battery having a superior efficiency of formation can be attained. This is due to the fact that an electrical current at the time of formation is dispersed and made to flow by the whisker- like projections 4 and so the formation reaction may not be concentrated at a specified location. In addition, since a variation in volume of the active substance 6 caused by reaction is made uniform, resulting in that the tube 7 may not be broken around the vane.

Title: Semiconductor substrate and manufacture thereof
Inventor: MOTOYAMA TAKUYUKI
IPC: H01L21/205
Filed: 1989-02-21
Abstract: PURPOSE:To prevent occurrence of dust when a semiconductor substrate is handled by coating the semiconductor substrate with resist with the exception of at least a peripheral part and the side face of an outer circumference and removing compound semiconductor layers at the above peripheral part and the side face of the outer circumference which are not covered with resist through etching treatment, thereby removing resist. CONSTITUTION:There is a compound semiconductor (GaAs) layer 3 on an Si single crystal wafer 2. Then the peripheral part of a substrate 1, the side face of an outer circumference, the rear of the substrate are free from the GaAs layer 3 and then a wafer 2 comes out on the surface. Then resist is applied on the semiconductor substrate (GaAs/Si substrate) with spin coating and its substrate is exposed through a prescribed mask pattern and is developed. Subsequently, the GaAs layer which is not covered with a resist layer is removed by the use of an etchant and after washing it with water, the resist layer that still remains is removed with an alkali developing solution and the semiconductor substrate 1 is obtained. In this way, a carrying arm, a holder, and the like do not come into contact with the above semiconductor layer and then an Si part that comes out on the surface comes into contact with its layer. This configuration decreases occurrence of dust and improves a yield of LSIs as well as light emitting devices that are manufactured into semiconductor substrates.

Title: Touch panel
Inventor: OBARA KEIJI
IPC: G06F3/041
Filed: 1988-02-24
Abstract: PURPOSE:To easily connect lead-out terminals with each other and reduce the time required by key scanning by applying voltages across both ends of linear conductors intersecting each other at right angles and calculating the pressed point of a touch panel from a change in the voltage value across both ends by a change in resistance value produced when the conductive bodies are brought into contact with each other. CONSTITUTION:Two sheets 1 and 2, on each of which plural parallel linear conductors x'1-x'4 and y'1-y'4 are wired, are faced to each other with a minute clearance between them in such a way that the corresponding conductors x'1-x'4 and y'1-y'4 of the sheets 1 and 2 can intersect each other at right angles. Under a condition where voltages are applied across both ends of the conductors x'1-x'4 and y'1-y'4, the touched point of this touch panel is calculated from the changes in voltage values across both ends of the conductors x'1-x'4 and y'1-y'4 by the changes in the resistance values which take place when the point is depressed by a finger, etc., and the conductors are brought into contact with each other. Therefore, the number of lead-out terminals of the conductors can be reduced and, even when the space among the conductors is depressed, the depressed point can be estimated. Thus connection between lead-out terminals becomes easier and the key scanning time can be reduced.

Abstract: PURPOSE: To improve thermal efficiency and fuel consumption by constituting the engine so that the oscillating angle of the external gear is zero when the center of the internal gear is on trochoid apsides line and the angle is the positive or negative maximum value when on trochoid minor axis line.  
     CONSTITUTION: In a rotary engine, when the internal gear 2 on the outside rolls on the external gear 1 on the inside and having the gear ratio of 3:2, the oscillating angle of the external gear 1 is zero when the center of the internal gear 2 is on the trochoid apsides line and the angle is the positive or the negative maximum value when on the trochoid minor axis. Therefore, the equation of the trochoid 4 is as follows: X=e cosA+Rcos(A/3+2B/3), Y=e sinA+Rsin(A/3+2B/3). Then the trochoid 4 corrected is asymmetric for minor axis, and the volume of the operation chamber at the expansion bottom dead point increases larger than that at the intake bottom dead point. Accordingly, the expansion ratio increases larger than the compression ratio, so thermal efficiency is improved, and fuel consumption is improved.
